Background Crenigacestat is a potent Notch inhibitor that decreases Notch signaling and its downstream biological effects. Here, we report the results from Part F of study 16F-MC-JJCA designed to evaluate the safety, pharmacokinetics (PK), and antitumor activity of crenigacestat with prednisone in advanced or metastatic cancer. The combination was planned to mitigate gastrointestinal toxicities. Methods Eligible patients (Study Part F) received crenigacestat loading dose (75 mg, escalating to 150 mg) administered thrice weekly (TIW) (F1) or twice weekly (BIW) (F2) for 2 weeks during Cycle 1, followed by 50 mg TIW from week 3 onwards. Prednisone was co-administered for 2 weeks in Cycle 1. Results Twenty-eight patients were enrolled; 11 in F1 (median age, 63 years), 17 in F2 (median age, 50 years). Dose-limiting toxicities were Grade 3 increased serum amylase and Grade 2 fatigue in F1, and Grade 4 hypophosphatemia and Grade 3 rash maculo-papular in F2. The maximum tolerated dose was 75 mg in F1 and 100 mg in F2. Best overall response was stable disease (F1, 6 [54.5%] patients; F2, 11 [64.7%] patients). Pharmacokinetic was dose proportional. Prednisone did not modify PK of crenigacestat, and both F1 and F2 achieved pharmacodynamics effects on evaluable tumor tissue samples. Conclusions This study demonstrated the potential use of prednisone to reduce gastrointestinal (GI) toxicities of a Notch inhibitor without affecting its PK. The safety profile observed was consistent with Notch pathway inhibitors, and the maximum tolerated dose was 75 mg TIW and 100 mg BIW in F1 and F2, respectively. ClinicalTrials.gov: NCT01695005.
